Jackson Police Chief Lindsey Horton said members of the SWAT team found the inmate, who the county coroner has identified as 21-year-old Markuieze Sherod Bennett, in a jail cell suffering from stab wounds. The Hinds County coroner said an autopsy determined Bennett died of blunt-force trauma the head.

"There was an inordinate amount of blood. They fought -- you could tell that," Horton said. "From all indications (the death) appears to be as a result of the confrontation."

Sheriff Tyrone Lewis said seven inmates were taken to a local hospital, where they were treated for unspecified injuries. Lewis said three of the inmates remained hospitalized Tuesday.

No jail employees were injured, authorities said.

Horton said there were more than 200 inmates in the jail pod when the fight broke out.

There are three pods -- A, B and C -- that make up the Hinds County Detention Center. In 2012, Pod C was destroyed by inmates after a disturbance that lasted about 10 hours.

After meeting for two hours in special session, the Board of Supervisors announced the emergency declaration. They said Pod A suffered the most damage during the disturbance, but Pod B was also damaged. Pod C, which has undergone repairs since the 2012 disturbance, will reopen and part of Pod B will be open to house inmates, county officials said.

Board of Supervisors President Darrel McQuirter said the county is looking into the possibility of building a new facility. He said the problems at the jail aren't related to management, they are because of the age and condition of the facility.

Supervisors also approved the purchase new radios and cameras for the Detention Center and voted to forego the normal bidding process.

Lewis held a news conference Tuesday morning about Domestic Violence Month, but would not discuss the fatal fight at the jail when he was asked about it by 16 WAPT's Tammy Estwick.

Outside the jail Monday night, Estwick asked Lewis if inmates had control of the jail.

"What we are able to gather from our intelligence is that they’re all back into their particular housing units … just sitting there, so we are again wanting to make sure we can do this in a safe and timely fashion," Lewis said.

Estwick posed the same question to Horton on Tuesday.

"Oh yeah, absolutely," Horton said. "Not so much the jail, as it was (inmates controlling) that pod."

Horton described the SWAT team's role.

"When they went inside (they) made sure those inmates knew they were there, first of all. They announced themselves," Horton said. "They tried to establish contact with them by way of one of our hostage negotiators. When that failed, the guards indicated that there was a concern for another inmate and that's when the SWAT team made the decision to breach and go in to save yet another (of the inmates) who could have been killed."

Tora Young, who said her son is jailed at the Detention Center, said she's concerned about his safety.

"Somebody needs to do something about this jail down here in Raymond," Young said. "You don't never know when your child is in danger. You never know when what's what, because, I mean, you try to talk to them. You try to help them -- and my child is 20 years old. You see what I'm saying?"

Horton said JPD is prepared to send prisoners to jails in other counties if it is deemed necessary.
